Reaction Steps

A mixture of ethyl 4-fluoro-3-nitrobenzoate 4.26 g, 2-isopropylimidazole 2.20 g, N,N-diisopropylethylamine 5.2 mL and acetonitrile 40 mL was heated under reflux for 24 hours. After distilling the solvent off, water was added to the residue and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate and removed of the solvent by distillation, to provide 4.95 g of the title compound.
